Another hostage death: The family of Kayla Mueller revealed devastating news yesterday. The American hostage held by ISIS was dead, her family said. The news came in a message from her captors over the weekend. The message sent to the family included photos, according to a U.S. official. Last week, ISIS clamed Mueller, an aid worker who was captured in northern Syria in 2013, had been killed during a Jordanian airstirke on Raqqa, but offered no proof. The White House blamed ISIS for her death, saying they were responsible for her well-being.
